Final answer:
During the formation of a polymer from monomers, an addition or condensation reaction is formed.
Step-by-step explanation:
During the formation of a polymer from monomers, an addition or condensation reaction is formed.
An addition polymer is formed by chain addition reactions between monomers that contain a double bond. The steps to form an addition polymer include initiation, propagation, and termination. On the other hand, a condensation polymer is formed when two different monomers react together and release some other small molecule as a product.
